I would like to use the LCD/touchscreen with the EMC disabled so I can use the I2C1 interface. The I2C1 data line is shared with the EMC DQM3 line so I cannot use both. I tried to disable EMC by not calling SystemSetupMemory() in sysinit_keil_mcb_18574357.c but this also seems to disable the LCD.  Can someone show me how to disable EMC but keep all LCD functionality for the MCB4357 board or just free up the DQM3 line so I can use I2C1? Thanks.
